Image-resize servlet

Hi,
I�ve been working on an image-resizing servlet on and off for quite some time now, and I just cant seem to get it to load the image correctly.
I guess its very simple once you figure it out. The following is the interesting part:
Image image = Toolkit.getDefaultToolkit().getImage("../pictures/pic" + pictureId + ".jpg");
MediaTracker tracker = new MediaTracker( new JFrame() );
tracker.addImage(image, 1);
// Load image
try {
tracker.waitForAll();
} catch (InterruptedException e) {}
// Scale image
image = image.getScaledInstance(width, height, Image.SCALE_DEFAULT);I then copy the Graphics from the Image to another Graphics before it is sent to the client (have some cache-stuff going on in the middle), but all images turn out beeing plain black.
Anyone with ideas/sample code?

hi flaperman
i did something similar in my resizing servlet:
BufferedImage image = ImageIO.read(new File(path));
Image im = image.getScaledInstance(width, height, Image.SCALE_FAST);
BufferedImage thumbnail = toBufferedImage(im);
ImageIO.write(thumbnail, "jpeg", response.getOutputStream());
i found the code of the method toBufferedImage() on the following page http://developers.sun.com/solaris/tech_topics/java/articles/awt.html
maybe this will help you. but i'm afraid it is slow and it seems to be leaking memory (a lot).
cheers

Proportional Image Resizing

Hi,
Description of the task:
I need to upload two images one is a full image and the other is a thumbnail representation of the same image of type jpg. I also need to ensure that all the uploaded images are within a given maximun size. For example:
Thumbs should be 76 x 55 pixels
FullSized should be 247 x 183 pixels
Task Achievements:
I've used the apachee commons package's FileItem class to handle retrival and storage of the image from the submitting servelet form.
Description of the Problem:
Don't know how to apply a proportional resize on the uploaded files (images) before storing them.
Other Questions:
1. Will the fact that conventional Buffered approach for reading files being not used hamper file manipulation?
2. Can a proportional Image resizing function be applied to images in java. (Similar to that of php)
3. Can an external php file be called or accessed from within java (a servlet) to perform the same functions of uploading an image and resizing it porportionally.

Ways to implement image resizing using plug-ins?

Hi Photoshop developers,
I'm a developer with a few Photoshop filter and selection plug-ins under my belt, and I have a good understanding of the SDK and tools and suites it provides. My next project is an algorithm for enlarging/resampling images to different pixel dimensions. I'm wondering if anyone has any suggestions for or experience with the best combination of plug-in types to implement this.
Clearly, I can't just write it as a filter plug-in, since there is no way to change the image dimensions from within a filter.
I'd like the resized image to remain within Photoshop (as a new window or in the original one), so an export plug-in on its own is not sufficient.
Import plug-ins seem promising, since they allow the creation of a new document of the required size. However, as best I can tell from the Photoshop 6.0 SDK documentation, import plug-ins cannot access the image data from other open documents (or even the clipboard), nor do they provide any support for channel ports and the Channel Port suite.
My best idea at this stage is to create an export plug-in to provide the user interface and calculate the resized image, and then an import plug-in to import the resized image back into a new window. (I'm supposing a further automation plug-in would then be written to perform this export/import sequence.) The difficulty I see with this approach is how to communicate the resized image data between the two plug-ins. Since the resized image will potentially be very large, the ideal solution would be to store it in channels managed by the Channel Ports suite. However, I cannot see how the channel ports created in the export plug-in could be communicated to and used by an import plug-in. The alternative would be for the export plug-in to save the resized image to a temporary file on disk, however this seems unnecessary.
So, my questions, specifically, are:
a) Is it possible to create new channels using the Channel Ports suite (sPSChannelPorts->New()) in one plug-in, and have those channels persist to be used in another plug-in?
b) If so, how would the channel ports be communicated between the plug-ins?
c) Alternately, are there any alternative architectures available for implementing an image-resizing algorithm using the plug-in types that are available for Photoshop developers.
Any responses would be greatly appreciated; I know this is a low-traffic forum...
Thanks,
Matthew.

I would make an automation plug-in and a filter plug-in. 1) Run the automation which runs your filter to gather current image information 2) Create a temp file of the new document 3) Make a new document 4) Call the filter again to reload the temp data on disk <[email protected]> wrote in message news:[email protected]... > Hi Photoshop developers, > > I'm a developer with a few Photoshop filter and selection plug-ins under > my belt, and I have a good understanding of the SDK and tools and suites > it provides.

Images as Buttons and Image Resizing in mxml

Sorry for all the questions but I've run into a problem when trying to create buttons that are just an image in mxml. When I first tried this I couldn't find a way to get the border around the button to dissapear so it ended up looking like my image had an extra black border around it. Then someone here suggested I just set the buttonMode property of an mx:Image to true which ended up working fine to a point. The problem I'm having is that even if I make the tabEnabled property of the image (that I'm using as a button) true, I can't tab over to it. Is there a way to either get rid of the black borders of a button or to make it so I can tab over to an image I'm using as a button?
My second question has to do with image resizing. Lets say I have an image of a horizontal line that I want to put at the top of the mxml page, and I want it to extend the full length of the page, even after the user has resized the browser. Is there a way to do that? I've tried putting the width as 100% or giving the image a "left" and "right" value so that presumably it would be stretched to fit within those but nothing has worked so far. Is there no way to do this or am I doing something wrong?
Thank you for any help you guys can give.

Of course, sorry about that. So the following is a barebones example of how I currently implement buttons and images as buttons:
<mx:Button id="facebookButton" icon="@Embed(source='image.png')" width="30"/>
<mx:Image buttonMode="true" id="button" source="anotherimage.png" enabled="true" click="{foo()}"/>
And within the image I've tried making the tabFocusEnabled property true but to no avail.
The following is how I've tried stretching out an image across the whole page:
<mx:Image source="yetanotherimage.png" width="100%" scaleContent="true"/>
<mx:Image source="yetanotherimage.png" left="10" right="10" scaleContent="true"/>
Is this more helpful?

Why won't Photoshop revert to earlier history state after image resize when scripted?

I've written an Applescript to automate watermarking and resizing images for my company. Everything generally works fine —　the script saves the initial history state to a variable, resizes the image, adds the appropriate watermark, saves off a jpeg, then reverts to the initial history state for another resize and watermark loop.
The problem is when I try not to use a watermark and only resize by setting the variable `wmColor` to `"None"` or `"None for all"`. It seems that after resizing and saving off a jpeg, Photoshop doesn't like it when I try to revert to the initial history state. This is super annoying, since clearly a resize should count as a history step, and I don't want to rewrite the script to implement multiple open/close operations on the original file. Does anyone know what might be going on? This is the line that's generating the problem (it's in both the doBig and doSmall methods, and throws an error every time I ask it just to do an image resize and change current history state):
 set current history state of current document to initialState

As many others here I use JavaScript so I can’t really help you with your problem.
But I’d like to point to »the lazy person’s out« – with many operations that result in creating a new file on disk I simply duplicate the image (and flatten in the same step) to minimize any chance of damaging the original file if the Script should not perform as expected.

Image resizing in Smartforms?? or ADOBE

Hello All,
I am working on creating a smartform. It includes displaying images in the output. There could be different
smartforms displaying the same image but with different sizes.
I know of the solution to resize the image using picture editor and upload using SE78, which is then accessed in the smartform. But I want to avoid multiple sizes of same images in the MIME repository.
Is there a possibility of image resizing in the smartform ? If yes, then how ? I have tried changing the DPI in General attributes of the graphic node in smartform but it does not resize the image.
If not, then is it possible in ADOBE forms ?

Permissions issue with image resize

Ok I'm hoping someone may be able to help with this because it is really frustrating.
I realise this issue has already been posted in these forums however there was no solution offered that has rectified it for me. I am getting an error when trying to display thumbnails "Error converting image (create thumbnail). The "" folder has no write permissions". And this error when trying to upload and resize images "Image upload error. Error resizing image: Error converting image (image resize). The "" folder has no write permissions. (IMG_RESIZE)". All folders on server have full read, write and execute permissions, so I am really confused why this happenning. I have removed and updated the includes folder on the server with no joy. I altered the tNG_custom.class.php, tNG_insert.class.php, tNG_update.class.php files to remove the tNG_fields line to just tNG as this was throwing errors with PHP5.3. I also changed everything else per http://forums.adobe.com/message/2357443#2357443.
This is the tNG execution trace (why the tNGUNKNOWN??):-

Is it the preg_split() that is causing the issues here??
Any Ideas?

Hello BoarderLineLtd
I have noticed that on some servers when you upload the first image to the images folder using the ADDT image upload function the thumbnail directory that gets written to the images directory is written but the permissions are not set.
If you use an FTP program such as CuteFTP or WSFTP to login to your web site you can manually set the permissions for the thumbnail directory.
This should eliminate the permissions error.

PSE newbie frustrated, please help with image resizing

Hi!
Tutorials aren't helping me, nor is trial and error. I just want to resize some photos I downloaded to my computer, then upload them to a website to use as my avatar or signature. There are specific pixel dimensions I must adhere to. I want to keep the photo in it's entirety, but when I resize it, it distorts a bit, looks fuzzy...
I can't figure out what the heck I am doing wrong. Some pictures turn out just fine and others look really bad. I know it can be done because I've seen the same pictures I'm trying to size, being used for the same thing I want to use them for, but theirs are clear, absolutely no distortion whatsoever. The pixel dimensions I have to work with are either 100x100, or 450 pixels wide by 90 pixels high.
I hope this made sense, I'm not sure how else to word it. Please forgive my ignorance, I've really been trying.
Thank-you
B

For an avatar it’s possibly best to crop to begin with so you get a true square.
Open the image and select the crop tool and change the aspect ratio to 1 x 1 or 5 x 5 then drag out a square and move the image around inside it or drag the bounding box borders until you have it looking as you want. Then click the green check mark.
On the top menu click Image > Resize > Image Size and in either the height or width box type 100 px (you only need to type the dimension once the other box will change to 100 automatically. Make sure you have the bottom three boxes checked:
Scale Styles
Constrain Proportions
Resample Image
With all three checked set the bottom dropdown to Bicubic and then hit OK.
If you want to apply some sharpening select Enhance on the top menu and choose Unsharp Mask.
Make sure the Radius is no more than 1.5 and use the amount slider to get the image looking as you want it then save.

Photshop CS6 image resizing tool.

Five time I have entered a support question but it does not seem to appear in the lists nor have I had a response, am I entering my request incorrectly?
My request is:
I have a PC using Windows 7. I have Photoshop CS6 which I have been using for some time. Very recently the image, image size tool has stopped working. I open the drop down window and the current size of my image is displayed. I then try and type the required changed size in the box but the box does not accept it. The size remains the same. I have un-installed and re-installed CS6 and put in all the latest updates. The first image I tried, it allowed me to change the size. The second image the resize tool would not allow any changes. We were back to where we started. Elsewhere on the support FAQs it was suggested such problems might be cured by deleting \adobe photo cs6 prefs.psp file. This I have done but still I cannot resize my images.
Please can someone help me??

If Photoshop has been working well for you then start acting strange the first thing that should come to you mind is your Photoshop preferences. Your Photoshop preferences are Photoshop setting made for your user ID for how you want Photoshop to behave. Each user ID has there own set of Preference files. These are not installed or removed when you Install or uninstall Photoshop. So if you un-install and re-install Photoshop your Photoshop preferences remain intact. If the Problem you are having is caused by a corrupt Photoshop preference file. You will still have that same problem. Did you try resetting your Photoshop preferences?
Though the Image size dialog is simple many users do not really understand everything about image resizing. Using a quick look at the image we see three section Top, Middle and bottom..
Top section is basicly image file size how many pixels are there in the image.
Middle Image Print Size.
Bottom Image Resize Image Controls.
To understand Image Resize you must start from the bottom. In the bottom control section Resample Image is the single control that governs the whole resizing process. When "Resample Image" is NOT checked all other controls have no roll in the resize process they are grayed out as is the top file size section. The file size will not change the pixel will not change. Note all that is grayed out in the above image. All that can be change is the print size. The middle section and all three sizes there are tied together as shown by the lines and link icon. Change one size there and Photoshop will calculate the other two and display the proper values. All thee setting in the center are sizes associated with length. Width number uints, Height number uints. and Resolution number Pixel/unit. Resolution therefore is pixels size and pixels have an aspect ratio. Most image pixel these days are square 1:1 aspect ratio. Photoshop support non square pixels but can only display image using square pixels display have.
So when Resample is not checked. The image has a Width with a fixed number Pixel, a Height with a fixed number Pixels and Pixel aspect ratio. Setting any one print dimension will also set the other two dimensions.
When resample is check the other controls in the bottom section become useable and so does the top file section. Normally you should check Constraint Proportions link Width and Height so your image will not distort during the resize. When you resample an image you wind up with an entirely new image with a different number of pixels. Some image quality has been lost for you either through way some details you had or created some details you did not have. The image quality will depend on the quality of the pixels you had and how well the interpolation method used worker with those pixels. IMO Adobe Bicubic Automatic is not a good general purpose method to it tend to add many artifacts to image that have been sharpened.
In newer version of Photoshop CC and CC 2014 Adobe has redesigned the Image Size dialog adding a preview image display. Made the dimension link icon the constrain proportion control when resample is checked. Also hid the scale style option under a gear icon in the upper right corner.

How to generate thumbnail of a image in servlet

hi
could anyone tell me how can we generate thumbnail of a image which is stored in server using servlet

Google for something like java image resize or java create thumbnail. Plenty of examples around.
See also http://today.java.net/pub/a/today/2007/04/03/perils-of-image-getscaledinstance.html
If you are quality conscious to the point that bicubic isn't enough, google for Lanczos algorithm. I don't know of a plug-and-play Lanczos Java implementation. I did one myself (company property, sorry) based on some other language version that google will find for you.

PSE5 Process Multiple Files Image Resize

I want to batch convert some TIFF files to JPG and make them all 300 ppi. I tried suing the Multiple file processor in the Editor just entering 300 in resolution and leaving width & height blank. I hoped it would perform the same process as going to image resize and and changing resolution with resample and constrain proportions turned off. Instead it has changed the ppi from 72 to 300, but kept the size the same i.e. has added lots of extra pixels making the file enormous.
The only way I can force it to shrink the image is to enter say 30cm as the width. The problem with this is twofold a) I have to trun all my photos so they are landscape b) if I have cropped a photo such that it doesn't have enough pixels to stretch then again it is getting resampled.
Is this a limitation of PSE5 that wouldn't be there in CS3 or am I doing something wrong? I only want to print tham out 15x10 but read I should resize everything to 300 ppi. To be honest I never did this before I had PSE and they seemed to come out OK from a Canon that saves the files as default 72 ppi but large dimensions. Maybe someone couldexplain in laymans terms why the photos need to be resized to 300 ppi anyway? Thank you

Well, you see, Process Multiple files is doing just what you asked it to do: it's
resizing the photos. But you don't really want to resize the photos, just change the ppi setting. Is there a particular reason you want them to be 300ppi? PPI is a setting that only matters for printing or if you are sending a photo somewhere that requires that marker to be set to 300. Your camera doesn't know anything about ppi, only absolute pixel dimensions (eg 2480 x 1795 or whatever).
When you go to print, however, your printer may prefer to have a higher pixel density, since it can play your pixels like an accordian: squash them closer together or spread them out thinner, depending on that ppi marker. The pixel density determines the inch/cm size of your print (at 72 ppi you'll get a print that's hugely bigger but less detailed; at 300 ppi a crisper smaller print.)
I'm wondering why you would want to batch convert a whole big bunch of images at once, though. It would help if you would explain just what you want to do with the photos that requires the 300 ppi.

Image Resize Menu not available

According to Mail Help, when I insert an image into an email, there is supposed to be an image resize menu in the lower right portion of the window and a message size indicator in the lower left of the window. Neither of these are appearing for me. I have tried attaching an image in a number of different ways with the "insert attachment at end of message" both on and off. Any ideas out there?

I've got the same problem. It only occurred after upgrading to Leopard.
Before it worked fine. (Leopard is for me not a success on this moment: my pages just stopped working, can't connect via bleutooth to my phone anymore using addressbook, eyeTV also stops at random and restarts are occurring often. I'm starting to get that 'trow this stupid thing out the window' feeling i had during my MS windows era.

Slideshow image resizing when adding new images

I am creating a series of slideshows on multiple pages. I created one slide show using the "basic" slideshow and resized it to the dimensions and settings I wanted. I have many pictures all of different proportion, therefore, I selected the "fill frame proportionally" so they would all fit the dimension I set. I wanted to use this first slideshow as a template for all of the rest. I added images to this first slideshow with no problems. All of my different sized images scaled or cropped to fit within the dimension I set. The problem comes in when I do two things: 1) When I add other images of different dimensions to this same slideshow gallery, they come smaller that the intended dimensions I set previous. I check the setting and it is still on "fill frame proportionally" similar to the first batch of pictures. 2) The second issue is when copy this slideshow as a template to other pages. When I try to replace or add to the slideshow gallery, the images come in cropped or smaller rather than filling the frame. Again, the settings are still the same from my very first slideshow that worked just as i intended.
I could resize all the images to all the same dimensions using another program like photoshop, but that is another step that is very tedious and it would seem that it should be something built into Muse.
Is there a way around this?. Am I doing something wrong? Or is this just one of those glitches that happens with Muse? I appreciate any help that I can get.
Thanks!

Hi, I got it to work like this:
Using background colours in Photoshop so that all sizes are the same in pixels. Then manually adjusting thumbnails by double-clicking on them so that a red square appears.
Cheers,
Elsemiek

Hi there Elsemiekagain,
I had to fiddle around with my slide show to get it to work. That is, it worked at first, then went funky, and I had to fiddle. So much fiddling that I can't possibly know what actually made it start to work again.
And to some degree, this is the way that I find Muse to be in general. That it requires finessing to get it to work as expected. This adds a good deal of time to every development project, though I am getting better at this with practice and experience.
Most of it is not even things that could be easily put in words as instructions, as many are nanced. But in fairness, this version of Muse is a complete code re-write this year. So we do need to cut Adobe some slack, and give the team time to iron things out.
